{"id":"CVE-2024-0668","state":"PUBLISHED","title":"Advanced Database Cleaner <= 3.1.3 - Authenticated(Administrator+) PHP Object Injection via process_bulk_action","description":"The Advanced Database Cleaner plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1.3 via deserialization of untrusted input in the 'process_bulk_action' function. This makes it possible for authenticated attacker, with administrator access and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.","publishedAt":"2024-02-05T21:22:03.271Z","updatedAt":"2026-04-08T17:28:47.158Z","severity":{"score":6.6,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["symptote Advanced Database Cleaner – Optimize & Clean Database to Speed Up Site Performance"],"affected":[{"vendor":"symptote","product":"Advanced Database Cleaner – Optimize & Clean Database to Speed Up Site Performance","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.1.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e0b8c24b-3e51-4637-9d8e-da065077d082?source=cve","https://plugins.trac.wordpress.org/browser/advanced-database-cleaner/tags/3.1.3/includes/class_clean_cron.php#L224","https://plugins.trac.wordpress.org/browser/advanced-database-cleaner/tags/3.1.3/includes/class_clean_cron.php#L298","https://plugins.trac.wordpress.org/changeset/3025980/"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:06:42.242Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/0xxx/CVE-2024-0668.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2024-0668","state":"PUBLISHED","datePublished":"2024-02-05T21:22:03.271Z","dateUpdated":"2026-04-08T17:28:47.158Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2024-01-17T20:53:53.251Z"},"containers":{"cna":{"title":"Advanced Database Cleaner <= 3.1.3 - Authenticated(Administrator+) PHP Object Injection via process_bulk_action","descriptions":[{"lang":"en","value":"The Advanced Database Cleaner plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.1.3 via deserialization of untrusted input in the 'process_bulk_action' function.
